COLUMN AND GAS CHROMATOGRAPHIC ANALYSIS. OF OIL OF WILD GINGER. IDENTIFICATION AND ESTIMATION OF SOME NEW CONSTITUENTS.

Gas chromatography mass spectrometry (GC/MS) analysis is an effective testing and troubleshooting tool for many manufacturers across industries, helping identify and quantify the materials that make up a sample or uncover contaminants that impact product quality. Additionally, gas chromatography can be used to determine vapor pressure, heat of solution, and activity coefficients. Industries often use it to monitor processes to test for contamination or ensure a process is going as planned. Chromatography can test blood alcohol, drug purity, food purity, and essential oil quality. Invented in the 1940s, gas chromatography has quickly become one of the central tools in analytical chemistry. Gas chromatography makes it possible to know what an essential oil contains by separating the oil into its individual components. Table 1 provides a quick reference to common questions that can be answered with the use of oil and condensate analyses. However, chemical analysis data, such as provided by gas chromatography, must be integrated with geological, engineering, and wellsite information to make these interpretations .
